SPECIFICATION forming part of llbetters- Patent N o. 741,350, dated October 13, 1903.

Application led January 18,1900. Serial No. 1,936. (No model.)

To @ZZ whom t may concern/.-

Be it known that I, ERNEST F. LLOYD, a citizen of the UnitedStates, residing at Fort W'ayne, in the county of Allen and State of Indiana, have invented certain new and use fnl Improvements in Dumping-Grids for Gas- Puriiierloxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to dumping trays or grids forgas-purifier bones.

The object of this invention is to provide for dropping or dumping the charge or layer of oxid of iron or other purifying substance on certain portions of the trays or grids above an openingr in the bottom of the purifier-box, thereby quickly providing an opening or passage-way through which the entire charge remaining on the 'layers of grids may be discharged.

My improved device isv applied to one or more sets of trays or grids, one above another, in a purifying box, and one or more devices may be used in different parts of the box.

Oxid of iron is now extensively used for purifying gas and is being employed in layers of several feet in depth. One or more. such layers may be used in a box. Much difiiculty and labor is involved in digging down from the top ofthe purifier t0 the layers of trays or grids and removing a section of the same in order to make a passage-way down to the bottom door of the box. If there are two or more layers and two or more sets of trays, the labor is much increased. By means of my improved dropping or dumping grids and connecting devices I overcome the difculty and labor and loss of time heretofore required in removing the oXid of iron to reach the outlet-door vfor discharging the layer or layers of oxid on the remaining grids into the cellar or any receiving-floor.

The devices and combinations of parts constituting my invention herein will be deiined in the claims.

I will now describe the details of construction of my improved mechanism by reference to the accompanying drawings, in which- Figure 1 represents a top plan view of an angle-iron frame and a pair of my hinged dumping-grids. Fig. 2 represents a sectional elevation of two frames and two pairs of dumping-grids adapted for use in a purifier-box. Fig. 3 represents anportion, as one end, Yof a purifier-box, showing my dumping-grids in position and a cellar or receiving-floor below the box. Fig. 4e represents a top plan view, and Fig. 5 represents an elevation, of the supporting Cotter-bar, on reduced scale, resting on the frame. Figs. G and 7 represent modifications of the devices for supporting the dumping-grids. Fig. S represents a perspective view showing a portion of a layer of grids for a purifying-box and containing swinging sections of grids embodying one form of my invention for dumping or dropping purifying material. Figs. 9 and l0 represent, respectively, a longitudinal and a transverse section of a sliding tray or grid, illustrating another form of my invention for dumping or dropping purifying material. Fig. 11 represents a top plan view of a sliding grid or tray adapted to be operated by a vertical shaft and pinion. Fig. 12 represents a top plan view, on reduced scale, of an angle-iron frame and a pair of my hinged dumping-grids with modified devices for supporting the same in a horizontal position. Fig. 13 represents an edge view of the grid and a side elevation of the supporting devices.

In carrying out my invention I use either a pair of swinging and dumping grids, as illustrated in Figs. 1 and 2, or a single dumpinggrid or a sliding grid or tray for dumpingthe purifying material, as illustrated in Figs. 9,

10, and l1. lVhile my swinging or sliding grids constitute an effective means for dumping or dropping the purifying material in one, two, or more layers of grids to form a passageway down to the bottom door of the purifierbox, I wish it understood that such grids and `their operating devices do not in any manner IOO and the discl1arge-door is placed in the bot-v tom of the box directly below the dumping or dropping grids, as illustrated in Fig. 3.

The frames A are preferably made of angleiron and in practice rest upon the same supports as are provided for the trays or grids, such as the brackets f, in a wellknown In each frame, according to one A form of my invention, I preferably arrange two swinging grids, as B B, with their free or swinging edges adjacent, as shown in Figs. l and 2, while their opposite outer edges are pivotally connected to the rods c, which are fixed in the angle-iron fralnes A and secured by nuts at their outer ends, as shown in Fig. l. Each swinging grid B is made with bars b and slots g, also with downwardly-projecting strengthening-ribs b', at their under sides, as shown in Fig. 2. The grids shown in the drawings are of cast-iron; but they may be made of wood, as is common construction for trays or grids, if preferred. The frame A instead of being made of angle -iron may also be made of wood. The two swinging grids B B are hinged at opposite ends of the frame and are supported in a horizontal position by the rod E, having secured to it a double cam or eccentric f.

A Cotter-bar D, having a central hub d, provided with an eye or hole for rod E and with the end hooks d', is seated in notches in the frame A, as shown in Fig. 5, and serves for supporting the rod E.

The operating-rod Eis provided at its upper end with a handle e, which in practice will project above the top layer of oxid of iron, and is also provided with a double eccentric button or catch f, which is secured to the rod by a tranverse pin 7i. This eccentric button 4o f rests upon the hub of bar D just below the dumping-grids B B when they are in the horizontal position, as shown in Fig. 2. The rod E is preferably made in two or three sections, as shown in Fig. 3, which sections are joined together by the socket-joints e and e, as shown in Figs. 2 and 3. The nut at each of the joints e and e" is made with a screwthreaded portion and also with a square socket fo1` receiving the squared end of the rod. Each nut is also held to a section of the rod by a transverse pin, as e". Instead of a detachable nut, one section of the rod E may be made with a forged socket to be engaged by the squared end of the adjoining section of rod. This jointed construction with detachable sections of rod is important for the purpose of permitting the uppersection of the rod to be removed so soon as the grids immediately below have been dumped. It is pref erable to'have the uppersection of the rod out of the way of the workmen when they are engaged in shoveling the oxid down through the discharge-opening. Since the cotter-bar D is connected to the rod E, it can also be lifted out after the grids have been dumped, as shown in Fig. S, and thus make a clear opening for discharging by shoveling the oxid Vof iron from the layer of grids. After the lower grids have been dumped the lowermost section of the rod and its @otter-bar can also be removed. The rod E is preferably provided at its lower end with a squared extension e4 below the nut a, as shown in Figs. 2 and 3, so that a wrench may be inserted through the door opening w and applied .to its squared end e4 for turning the rod, and thereby disengaging' the eccentric button f from the grids, thus permitting them to swing downward and dump their charge of material. The eccentric buttons f may be so set around rod E that a partial turn of the rod will iirst release the lower set of grids and then a further turn will release the upper grids, or vice versa, so that their charges shall be dumped in succession. This arrangement, however, is not essential, as both upper and lower sets of grids may be dumped at the same time and by a single quarter-turn of the rod E.

The purifier-box F is constructed with a sealing channel or gutter f/ and with interior supporting-brackets f in the usual manner. The cover G is applied and rests in the sealing-channel in the usual manner. An opening is provided in the bottom of the box immediately below the dumping-grids and is closed by a hinged cover H, which is secured by a locking-bar h, a swinging latch 7L, and a screw h'" in a well-known manner. The door when opened commonlyswings downward, so that the spent oxid may be discharged into the cellar M. The purifier-box is commonly supported on columns L, and a cellar M will be made of a sufficient depth, such as ten or twelve feet, for receiving the spent oxid and permitting it to be shoveled and spread into layers and revivified or allow means for its removal. The frames A, containing the dumping-grids B B, are supported upon the brackets f, secured to the sides of the box and 'to columns suitably placed in the interior of the box.

Instead of using a vertical operating-rod E with a catch for supporting the girds I may use a horizontal rod extending through the side of the box and adapted to be shoved in or pulled out for engagement with or disengagementfrom the edges of the trays, as shown in Figs. 6 and 7. The rod .I may be longer than here shown and in practice will pass through a stuffing-box in the side of the purier and extend thence to a bracket or hanger secured to the frame A. Other devices may be used instead of the cotter-bar 9, as will be hereinafter more fully described.

In the modified form of my dumping or dropping grid I construct a frame A', having a guideway a for receiving the sliding grid or tray B2. This grid B2 is made with a central longitudinal rackbar b, into which meshes a pinion g on the horizontal shaft E. The horizontal shaft E is supported in hangers u, secured to the frame A', as shown in IIO wisse Fig. l0, and in practice projects through the side of the puriiierfbox, where the outer end will be provided with a hand-wheel or other means for turning it. (Not here shown.)

Instead of constructing a rack-bar on the under side or the sliding grid it may be secured to one end thereof and be provided with lateral teeth, as shown in Fig. ll. With this construction the vertical shaft E2, provided with a pinion g2, will be arranged for operating the grid B2.

It will be evident that these sliding grid sections may be readily opened or slid back from the opening in the layer of trays for dropping the purifying material through the discharge-opening in the bottom of the box.. They will serve substantially the same purpose as the swinging and dumping grids above described and are within the scope of my invention for dumping or dropping the purifying material to form an opening or passageway down to the discharge-door in the bottom of the box, so that l[he whole layer of purifying material may be readily discharged, by means of shovels,through such passage. It is evident that this advantageous result is attained without obstructing or limiting the effective purifying area in the purifier-box.

In Figs. 12 and I3 I have shown a modified arrangement of the operating-rod provided with the cam or catch for supporting the grids in a horizontal position and have dispensed with the Cotter-bar. In this modiiied arrangement I provide two vertical operatingrods E3, passing down through the frame A on a line with the meeting edges of the grids B and B. To such rodsES are secured the two cam-shaped latches or buttons f as clearly shown in Figs. 12 and 13, which when turned inward on both sides will securely support both of the grids in a horizontal position. In Fig. 13 the lower section of the rod Ils below the grid is provided with a solid socket e4, forged on the end of said section, into which iitsl the squared end of the upper section of the rod. This provides for convenient removal of the different sections of the operating-rod when desired.

From the above description of the construction and arrangement of the devices it is thought that their operation will be fully understood Without further description.

The devices are very simple in operation and are very effective and advantageous in saving of time and labor in the removal of spent oxid from the puriiiers.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-r l.l The combination with a purifier-box having a layer of grids and a bottom door, of a hinged dumping-grid, a supporting cotterbar, an operating-rod adapted to turn in said bar, and having a button or catch for engaging the edge of said grid, substantially as described.

2. In a gas-puriiier box, the combination With a layer of trays or grids, `of a pair of hinged sections therein meeting at their free inner edges, a vertically-supported turning rod, having a button or catch adapted to engage the meeting edges of said hinged sections, and a bottom door directly below the hin ged sections for making apassage-way and permitting the spent material to be discharged at the bottom of the box, substantially as described.

3. The combination with a purifier-box, of a hinged dumping-grid, a supporting cctterbar, an operating-rod adapted to turn in said bar, and having a button or catch for engaging the edge of said grid, substantially as described.

4. In a gas-purifier box, `the combination with a frame, of a pair of dumping-grids hinged at their outer edges to the frame, a @otter-bar supported on said frame, an operating-rod, supported and turning in said bar, between the edges of the grids, and having means for engaging and holding the grids or disengaging them for dumping their charge, substantially as described.

5. In a gas-purifier box, the combination with the frame A, supported therein, of a pair of dumping-grids, as B, B', hinged respectively at c, c, in said frame, a cotter-bar D, resting on the frame, an operating-rod E, having a button or catch f, and supported in said bar, substantially as described.

6. In a puriiier-box, the combination with two or more frames, and pairs of dumpinggrids hinged in said frames, one above another, of a Cotter-bar resting on each frame, an operatingrod, having means for engaging with said grids for supporting them, and one or more disconnecting-joints, whereby one or more sections of said rod may be removed when required, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
